Flodding log of vcenter

Hi,

we are running PRTG 14.1.8.1371 stable with a vmware vCenter 5.5. We use the SOAP Sensor for monitoring it. Today we got a problem on the connected hosts that told us problems with statistics data. Over vmware support we came to the end that the cause of this was a full log database on the vcenter. After clearing this, we figured out that the PRTG sensor is causing vmware to give an entry for this poll in the logfile. After a while (when polling every 60 seconds) this reached much rows as you can imagine - every 60 seconds there are 4 entries for each host.

This flooding on one hand is negative for performance and space in database, but also a problem for accessing "real" log messages in middle of this. What is the way to get rid of this ?!

Update to this issue:

Update 15.3.19 (September 2015) did implement the new VMware (SOAP) sensor:

"The VMware Datastore (SOAP) sensor monitors the disk usage of a VMware data store. This sensor type supersedes the outdated SSH VMWare ESX(i) Disk sensor. The VMware (SOAP) sensors now also support session pooling. You can define session pooling in the device settings."

- see PRTG History.

Hi,

PRTG is designed to work as stateless as possible when querying information from a target machine. Therefore currently these sensors are logging in and out for each scan. In this case this produces a lot of 'noise' in the log-files as each login and -out action is written in the log-files of the ESX(i)-servers or the vCenter-Server. Unfortunately it is not possible to reduce this 'noise' by reducing the log-level on the VMWare machines.

We are aware of this issue and the problems that can occur from it. Currently we are redesigning our VMWare-Sensors to use a 'Session-pooling' in order to reduce the number of log-entries as well as the transmitted data between VMWare and PRTG on the one hand and to improve performance on the other hand.

It is estimated to release the new sensors in Q3/2014.

Kind Regards

Dieter

Hi Jeremy,

I'm sorry but there is still work in progress. I think as a modest estimate I can give you the end of Q1/2015 or Q2/2015.

Kind regards

Hi,

since this problem now had it's "birthday" and is a real problem that penetrates the "outer infrastructure", it would be VERY appreciated if it would really be released in Q2 latest. I think there are more than just us two guys that are affected by this, and it has a big impact when it comes to described problem it should be more priorized in my opinion as some new features you implemented.

I am really looking forward getting good news on this soon :)

Regards Dominic

Dominic, we actually have the VMware Sensors in Beta Test, that reduce these entries by using a session pooling. If you'd like to participate in the beta test, please get in touch with us with an email to [email protected] with a reference to this KB-Thread.
